DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] The present invention provides a hydrogen storage tank anti-collision structure, such as Figure 1 and Figure 2As shown, it includes a tank body 1, an external connection pipe 2 is connected to the opening of the tank body 1, a limiting rod 3 is connected to the tail of the tank body 1, a first baffle 4 and a second baffle 5 are respectively sleeved at the opening and the tail of the tank body 1, the first baffle 4 and the second baffle 5 are both arranged in a circular ring shape, the first baffle 4 is sleeved on the surface of the external connection pipe 2, the second baffle 5 is sleeved on the surface of the limiting rod 3, an outer protective frame and an inner protective frame are arranged between the first baffle 4 and the second baffle 5, the outer protective frame is located outside the inner protective frame, and the inner protective frame includes an inner ring 6, and the inner ring 6 is sleeved on the outer circumferential surface of the tank body 1, multiple rollers 7 are installed on both sides of the inner ring 6 by screws, and the outer circumferential surface of the roller 7 is in contact with the outer circumferential surface of the tank body 1, and the inner ring 6 rotates on the outer circumferential surface of the tank body 1 by using multiple rollers 7, and the rollers 7 are made of rubber material. The outer side surface of the first baffle plate 4 is provided with a collar 22 which is sleeved on the external connecting pipe 2, and the collar 22 is made of rubber material. The outer side surface of the second baffle plate 5 is provided with a screw sleeve 23 which is spirally sleeved on the surface of the limiting rod 3, and the inner side surface of the screw sleeve 23 is in contact with the outer side surface of the second baffle plate 5. After the first baffle plate 4 is sleeved on the outer side surface of the circumference of the external connecting pipe 2, the external connecting pipe 2 is spirally installed at the opening of the tank body 1. At this time, the first baffle plate 4 is correspondingly located at the opening of the tank body 1. At this time, the second baffle plate 5 is correspondingly sleeved on the surface of the limiting rod 3 at the tail of the tank body 1, and the second baffle plate 5 is installed at the tail of the tank body 1 by the spiral cooperation between the screw sleeve 23 and the limiting rod 3. The annular first baffle plate 4 and the second baffle plate 5 make it convenient for the tank body 1 to be in a lying state. When external components impact the surface of the outer protective frame, the impact force causes the outer protective frame to drive the first baffle plate 4 and the second baffle plate 5 to roll. The rolling of the first baffle plate 4 and the second baffle plate 5 drives the tank body 1 itself to roll. The outer protective frame and the inner protective frame are used to absorb the impact force, and the impact force is eliminated by rolling, so as to avoid external components from hitting the surface of the tank body 1, thereby facilitating anti-collision protection for the horizontal tank body 1.

[0024] The tank body 1 is vertically installed on the ground using a limiting rod 3. At this time, the first baffle 4 is horizontally located on the top of the second baffle 5. The cooperation between the screw sleeve 23 and the limiting rod 3 makes it convenient for the second baffle 5 to support the first baffle 4 using the outer protective frame. When external components impact the surface of the outer protective frame, the outer protective frame and the inner protective frame cooperate to absorb the impact force to avoid the impact force directly acting on the surface of the tank body 1. If the impact direction of the external component is tangent to the outer side of the outer protective frame, the impact force causes the outer protective frame to drive the first baffle 4 and the second baffle 5 to rotate, and the rotating outer protective frame drives the inner protective frame to rotate on the surface of the tank body 1. The impact force of the external components is eliminated by rotation and buffering, which facilitates the anti-collision protection of the upright tank body 1.

[0025] exist Figures 2 to 4In the embodiment, the inner protective frame includes a plurality of buffer components, and the buffer components include two opposite sliding bars 8. The surface of the sliding bar 8 is provided with side grooves corresponding to the inner ring 6. The sliding bar 8 slides on the surface of the inner ring 6 using the side grooves, and the sliding bar 8 does not contact the outer side surface of the circumference of the tank body 1. A pressure bar 9 is provided between the two sliding bars 8. The ends of the pressure bar 9 are provided with a first rotating plate 10 and a second rotating plate 11. The first rotating plate 10 and the second rotating plate 11 correspond to the two sliding bars 8 one by one respectively. The outer ends of the first rotating plate 10 and the second rotating plate 11 are both sleeved on the ends of the pressure bar 9. Insertion rods 12 are fixed on the sides of the first rotating plate 10 and the second rotating plate 11, and the insertion rods 12 are correspondingly inserted into the ends of the sliding bars 8. When the impact force of external components causes the pressure rod 9 to approach the inner ring 6, the moving pressure rod 9 drives the outer ends of the first rotating plate 10 and the second rotating plate 11 to approach the inner ring 6. Since the insertion rods 12 at the bottom ends of the first rotating plate 10 and the second rotating plate 11 are respectively inserted into the ends of the two sliding rods 8, and the sliding rods 8 are slidably connected to the surface of the inner ring 6 using the side grooves, the moving pressure rod 9 causes the first rotating plate 10 and the second rotating plate 11 to rotate, and the two sliding rods 8 are separated from each other through the rotation of the first rotating plate 10 and the second rotating plate 11.

[0026] The buffer component includes an arc plate 13, the outer concave surface of the arc plate 13 is in contact with the outer circumferential surface of the pressure rod 9, and a plurality of springs 14 are arranged between the arc plate 13 and the inner ring 6, the outer end of the spring 14 is connected to the inner convex surface of the arc plate 13, and the inner end of the spring 14 is connected to the outer circumferential surface of the inner ring 6. When the pressure rod 9 approaches the inner ring 6, the moving pressure rod 9 drives the arc plate 13 to approach the inner ring 6, and the moving arc plate 13 cooperates with the inner ring 6 to squeeze the plurality of springs 14, and the elastic force of the spring 14 is used to absorb the impact force of external components on the pressure rod 9, and the rotation of the first rotating plate 10 and the second rotating plate 11 facilitates the sliding rod 8 to disperse the impact force, thereby ensuring the anti-collision effect of the tank body 1.

[0027] exist Figure 3 and Figure 4 In the embodiment, the inner ring 6 is fixed with side rods 15 on both sides, the side rods 15 correspond to the arc plate 13, and a plurality of supporting rods 16 are fixed on the surface of the side rods 15. The inner convex surface of the arc plate 13 is fixed with a sleeve 17 corresponding to the supporting rod 16, and the sleeve 17 is correspondingly sleeved on the surface of the supporting rod 16. When the pressure rod 9 approaches the inner ring 6, the moving pressure rod 9 drives the arc plate 13 to move synchronously, and the arc plate 13 drives the sleeve 17 to approach the supporting rod 16, until the pressure rod 9 cannot continue to approach the inner ring 6, and the inner ring 6 uses the plurality of supporting rods 16 on the side rods 15 to limit the sleeve 17, so as to prevent the arc plate 13 from deflecting during the movement. Both ends of the pressure rod 9 use the first rotating plate 10 and the second rotating plate 11 to correspond to the end of the slide bar 8, and the first rotating plate 10 and the second rotating plate 11 limit the pressure rod 9, and the supporting rod 16 and the sleeve 17 cooperate to limit the pressure rod 9 outside the arc plate 13, so as to prevent the pressure rod 9 from deflecting in the impact of external components.

[0028] exist Figure 1and Figure 5 In the embodiment, the outer protective frame includes a plurality of outer arc frames 18, and the plurality of outer arc frames 18 correspond to a plurality of buffer components one by one. The outer arc frames 18 are correspondingly sleeved on the outside of the pressure rod 9 and the sliding rod 8, and two adjacent outer arc frames 18 are connected by spring plates 19. The outer arc frames 18 are correspondingly clamped on the outside of the pressure rod 9. When the external component impacts the outer arc frame 18, the outer arc frame 18 approaches the inner ring 6 under the impact force, and the moving outer arc frame 18 drives the pressure rod 9 to approach the inner ring 6. The moving rods 20 are fixed on both sides of the outer arc frame 18, and the inner sides of the first baffle 4 and the second baffle 5 are provided with sliding grooves 21 corresponding to the moving rods 20. When the impact force causes the outer arc frame 18 to approach the inner ring 6, the moving outer arc frame 18 slides inside the sliding groove 21 using the moving rod 20 at the end, and the outer arc frame 18 pulls the spring plates 19 during the movement, and the impact force of the external component is absorbed by the elastic force of the spring 14 and the spring plates 19.

[0029] The present invention also provides a liquid-cooled hydrogen storage tank, comprising a cylindrical tank body 1 and the above-mentioned hydrogen storage tank anti-collision structure.

[0030] Working principle of the present invention:

[0031] Reference Figures 1 to 5 As shown, after the first baffle 4 is sleeved on the outer side surface of the circumference of the external connecting pipe 2, the external connecting pipe 2 is spirally installed at the opening of the tank body 1. At this time, the first baffle 4 is correspondingly located at the opening of the tank body 1. At this time, the second baffle 5 is correspondingly sleeved on the surface of the limiting rod 3 at the tail of the tank body 1, and the second baffle 5 is installed at the tail of the tank body 1 by utilizing the spiral cooperation between the screw sleeve 23 and the limiting rod 3.

[0032] When the impact force of external components causes the pressure rod 9 to approach the inner ring 6, the moving pressure rod 9 drives the outer ends of the first rotating plate 10 and the second rotating plate 11 to approach the inner ring 6. Since the bottom ends of the first rotating plate 10 and the second rotating plate 11 are respectively plugged with the rods 12 at the ends of the two slide bars 8, and the slide bars 8 are slidably sleeved on the surface of the inner ring 6 using the side grooves, the moving pressure rod 9 causes the first rotating plate 10 and the second rotating plate 11 to rotate, and the two slide bars 8 are separated from each other through the rotation of the first rotating plate 10 and the second rotating plate 11. When the pressure rod 9 approaches the inner ring 6, the moving pressure rod 9 drives the arc plate 13 to approach the inner ring 6, and the moving arc plate 13 cooperates with the inner ring 6 to squeeze multiple springs 14, and the elastic force of the springs 14 is used to absorb the impact force of external components on the pressure rod 9, and the rotation of the first rotating plate 10 and the second rotating plate 11 facilitates the sliding slide bar 8 to disperse the impact force, thereby ensuring the anti-collision effect of the tank body 1.

[0033] When the external component impacts the outer side of the outer arc frame 18, the outer arc frame 18 approaches the inner ring 6 under the impact force, and the moving outer arc frame 18 drives the pressure rod 9 to approach the inner ring 6. The outer arc frame 18 is fixed with moving rods 20 on both sides, and the inner sides of the first baffle 4 and the second baffle 5 are provided with sliding grooves 21 corresponding to the moving rods 20. When the impact force causes the outer arc frame 18 to approach the inner ring 6, the moving outer arc frame 18 slides inside the sliding groove 21 using the moving rod 20 at the end, and the outer arc frame 18 pulls the spring sheet 19 during the movement, and the impact force of the external component is absorbed by the elastic force of the spring 14 and the spring sheet 19.

[0034] The annular first baffle plate 4 and the second baffle plate 5 make it convenient for the tank body 1 to be in a lying state. When external components impact the surface of the outer protective frame, the impact force causes the outer protective frame to drive the first baffle plate 4 and the second baffle plate 5 to roll. The rolling of the first baffle plate 4 and the second baffle plate 5 drives the tank body 1 itself to roll. The elastic force of the spring 14 and the shrapnel 19 is used to absorb the impact force, and the impact force is eliminated by rolling, so as to prevent external components from hitting the surface of the tank body 1, thereby facilitating anti-collision protection of the horizontal tank body 1.

[0035] The tank body 1 is vertically installed on the ground using the limiting rod 3. At this time, the first baffle 4 is horizontally located on the top of the second baffle 5. The screw sleeve 23 cooperates with the limiting rod 3 to facilitate the second baffle 5 to support the first baffle 4 using the outer protective frame. When external components impact the surface of the outer protective frame, the impact force is absorbed by the elastic force of the spring 14 and the spring sheet 19 to prevent the impact force from directly acting on the surface of the tank body 1. If the impact direction of the external component is tangent to the outer side of the outer protective frame, the impact force causes the outer protective frame to drive the first baffle 4 and the second baffle 5 to rotate. At this time, the outer arc frame 18 uses the buffer component to drive the inner ring 6 to rotate on the surface of the tank body 1. The impact force of the external component is eliminated by rotation and buffering, which facilitates the anti-collision protection of the vertical tank body 1.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
